Question

A study of a telemarketing company’s data showed that sales are only made when customers stay
on the line longer than one minute. The probability that customer stays on the line and a sale is
made is 1.5%. The probability of a sale occurring given the customer has stayed on the line longer
than one minute is 20%.
What is the probability that a customer stays on the line for longer than one minute?
